Abstract :
Continuous Variable (CV) Quantum Key Distribution (QKD) has the advantage of high raw bit rates due to the high efficiency and high bandwidth of homodyne detection and ease of integration with existing communications infrastructure. CV protocols that employ Post-Selection (PS) [1] - a classical filtering of the measurement results - enjoy additional advantages in terms of versatility and reconciliation efficiency.
